If budding, eco-minded designers need another reason to enter the fourth Red Carpet Green Dress competition, ELLE.com has exclusively learned that Vivienne Westwood will be a mentor to the winner. Additionally, she will act as a judge along with a prestigious panel that includes Suzy Amis Cameron (founder of RCGD and co-founder of the MUSE School CA), Lewis Perkins (of Cradle to Cradle Products Innovation Institute), and Zem Joaquin (founder and CEO of Ecofabulous.com). The group will choose from gown sketches to pick an up-and-comer to create a sustainable dress that will be worn by a to-be-annouced celebrity at the 2013 Oscars. Westwood will help the designer execute his or her vision.

"We are at war with our environment and our future is unsteady," said Westwood. "In order for a shift to occur we must make informed decisions to live more harmoniously with our planet, and I've joined Red Carpet Green Dress because its message aligns with this idea."
